SEPARATING APPARATUS FOR PAPER-PULP, &c., SUSPENDED lN LlQUlDS.

Application filed January 25, h3g7. Serial No. 225,456. (No model.) Patented in England November 11, 1886, No. 14,603; in France November 11, 1886, No. 166,786; in Austria-Hungary November 11, 1886; in Belgium November 11, 1886; in Germany November 12, 1886, No. 5,188, and in Italy December I, 1886, XX, 20,760. I

ToaZZ whom it may concern.-

Be it known that I, RUDoLF KRON, a citizen of the Republic of Switzerland residing at Golze rn, Kingdom of Saxony, Germany, have invented certain new and useful Improvements in a Separating Apparatus for Paper-Pulp and other Substances Suspended in Liquids, of which the following is a specification, and in which- Figure 1 is a longitudinal vertical sectional sponding parts in all the figures.

My invention has relation to machines for u separatinggranular or fibrous solid bodies suspended in fluids from the said fluids; and it consists ,in the improved construction and combination of parts of such a machine, in which a comparatively large straining-surface is obtained in a small space, and in which the strainingsurface may be beaten or vibrated for the purpose of preventing clogging of the apertures in the same, the machine being especially adapted for straining paper-pulp, celluloid-pulp, or coloring-materials dissolved in Water, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates a tank or box having a suitable outlet,f, and having a straining-bottom, S, of a suitable perforated material, dividing the tank or box into an upper and a lower compartment, respectively lettered a and of. The straining-bottom is shaped with corrugations of different shapes, the corrugations shown in Figs. 1 and 2 being triangular in section, the

corrugations shown in Fig.3 being waved, in

Fig. 4 cog-shaped or rectangular, and in Fig. 5 triangular with open upper edges, and a heater, B, is suspended below the bottom, and

is formed with suitable corrugations or serra tions corresponding in shape to the corrugations of the straining-bottom, and projecting up into the same, having a'small spaceleft between them. This heater is suspended by in the straining bottom and again drawn down,

Pipesb extend from the bottoms of the corrugations in the strainer and through suitable apertures or slots, 2', in the beater and through the bottom of the tank, having suitable cocks, h,'at their lower ends, so that .whatever collccts in the bottoms of the corrugations may be drawn off through these pipes.

In Fig. 5 is shown a forrnof straining-bottom having the upper edges of the corrugations extending up above the surface of the fluid in the tank, and having the said. edges open, so that the spaces between the strainer and the corrugations upon the beater maybe easily cleaned, and the strainer-sections may be removed separately, while in the other forms shown the entire bottom must be removed for the purpose of cleaning or repairing it.

In all the forms shown from Figs. lto 5, inclusive, the corrugations run transverse to the tank; but they may run longitudinally to the tank, if desired, as shown in Figs. 6 and 7,

when the beater is reciprocated transversely instead of longitudinally, as in the other forms.

It will be seen that by having the strainingbottom corrugated a larger straining-surface is gained in a comparatively small space, and that the reciprocating beater having its ribs or corrugations projecting up into, the corrugations of the strainer, it will continually beat the said strainer and prevent any objects from lodging in the apertures of the same. The fluids may be drawn off through the outlet, and whatever large objects remain upon the strainer will fall to the bottoms of the corrugations, and may be either drawn off through the pipes or be otherwise removed.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a machine for straining or separating solids from the fluids in which they are suspended, the eombination of a tank having a straining-bottom formed with corrugations with a beater having corresponding corrugations or ribs projecting into the corrugations of the straining-bottom and having means for being reciprocated, as and for the purpose shown and set forth.

2. In a machine for straining or separating solids from the fluids in which they are sus pended, the combination of a tank having an RUDOLF KRON.
